Overview

AI-generated overview

Local MCP server that lets an assistant encode and decode Base64, URL-encoded strings and HTML entities.

What you can do
  • Encode text to Base64 and decode Base64 back to plain text
  • URL-encode and decode URL-encoded strings
  • Escape HTML special characters and decode HTML entities to plain text
When to use it
Useful when you need quick, offline conversions while working in an IDE or chat client: turning payloads into Base64, reading encoded strings, or cleaning up URL and HTML-escaped text.
Requirements
Runs as a local stdio process, typically launched with npx from the npm package base64-forge-mcp; needs Node.js and network access for the first package download. No accounts, API keys or environment variables are declared.
Before you install
Conversions are local and stateless, but encoded data passes through the assistant's context, so avoid pasting secrets or credentials into encode/decode requests. The README's example tool name differs from the listed tool names, so verify the actual tool names after connecting.

Installation

In SourceWeft

  1. Open Base64 Forge Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
